Selling as upgrading to a unit that is able to drive my new HE-6 headphones adequately (this inability isn't really a black mark against the Xonar, the HE-6 are notoriously difficult to drive as they are a very low sensitivity can, the Xonar can drive basically anything else extremely well).

Purchased five months ago or so from Computer Lounge, so warranty still in effect for some six months or so yet. In pristine condition, a very nice unit indeed that competes well with offerings at least twice its price). More information here.
